Aqua-bis-(4-fluoro-benzoato-κO)bis-(nicotinamide-κN)copper(II) nicotinamide hemisolvate trihydrate
Abstract:
The asymmetric unit of the title compound, [Cu(C(7)H(4)FO(2))(2)(C(6)H(6)N(2)O)(2)(H(2)O)]·0.5C(6)H(6)N(2)O·3H(2)O, contains two aqua-bis-(4-fluoro-benzoato)bis-(nicotinamide)-copper(II) mol-ecules, one nicotinamide solvent mol-ecule and six water mol-ecules. The Cu(II) ion is coordinated by two O atoms from two 4-fluoro-benzoate ligands, two N atoms from two nicotinamide ligands and one water O atom in a distorted square-pyramidal geometry. In the crystal, O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonds consolidate the crystal packing, which also exhibits π-π inter-actions between the aromatic rings [centroid-centroid distances 3.692 (2)-3.794 (2) Å].

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...

Nomenclature of Carboxylic Acid Derivatives: Amides and Nitriles
The IUPAC and common names of amides are derived from the parent carboxylic acid, by replacing the suffix “oic acid” and “ic acid,” respectively, with “amide.” In the following example, the IUPAC name ethanamide is derived from ethanoic acid, and the common name, acetamide, is obtained from acetic acid.
